Standard Classification System for and Basis for Specification for Sulfone Plastics (SP)
2021
8
ASTM Vol.08.03 (2022)
This classification system covers sulfone plastics suitable for injection molding and extrusion. Sulfone polymers, being thermoplastic, are reprocessable and recyclable. This classification system allows for the use of reprocessed or recycled sulfone polymer materials. The properties included in this standard are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using the suffixes in Section 5. See Guide D5740. This classification system and subsequent line callout (specification) are intended to provide a means of calling out sulfone plastics used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastics field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this standard.
